Support authentication in the fluent source

[jszwedko]

As part of #419 we are adding a fluent source, but chose not to include authentication in the initial implementation due to the additional work it will require. This issue represents that work.

Please leave a 👍 or comment below if you would find this support useful.

@jszwedko Hi! Also, what about compression btw? Is it supported, will be supported?

Cause sending side supports it - https://docs.fluentd.org/output/forward#how-to-enable-gzip-compression

Update:
Nevermind, i've found the code and see it is gonna be supported. Thx)

@jszwedko Thanks a lot for supporting the fluent source in Vector. Is there any rough estimation on supporting authentication in the fluent source?

[jszwedko]

No estimate on timeline unfortunately. We'd be happy to see a contribution though if someone is motivated.
